WARNING
Operation of appliances with a blocked common vent may lead to serious injury or death. Safety devices must be implemented to prevent blocked common vent operation. If safe operation of all appliances connected to a common vent cannot be assured, including prevention of spillage of flue gasses into living spaces, common venting should not be applied, and appliances should each be vented separately.
AVERTISSEMENT
Le fonctionnement des appareils avec un système d’évacuation bloqué peut provoquer des blessures graves, voire la mort. Des dispositifs de sécurité doivent être installés pour éviter le blocage des systèmes d’évacuation. Si le fonctionnement de tous les appareils connectés à un système d’évacuation commun ne peut pas être assuré, y compris la prévention de la dispersion des gaz toxiques dans les espaces habités, on ne devrait pas installer un système d’évacuation commun et chaque appareil devrait être ventilé séparément.
It is for this reason that, in addition to following proper vent sizing, construction and safety requirements from the National Fuel Gas Code, ANSI Z223.1 or in Canada, from CSA B149.1 as well as all applicable local codes, it is required that installers provide some means to prevent operation with a blocked common vent. It is suggested that a blocked vent safety system be employed such that if the switch from one appliance trips due to excessive stack spill or backpressure indicating a blocked vent condition, that all appliances attached to the vent be locked out and prevented from operating. As an additional precaution, it is recommended that a Carbon Monoxide (CO) alarm be installed in all enclosed spaces containing combustion appliances. If assistance is required in determining how a blocked vent safety system should be connected to a product, please call Applications Engineering (see back cover for info).
Refer to the installation and operating instructions on all appliances to be common vented for instructions, warnings, restrictions and safety requirements. If safe operation of all appliances connected to a common vent cannot be assured, including prevention of spillage of flue gasses into living spaces, common venting should not be applied, and appliances should each be vented separately.
3.4.2 Inspection of Commonly Vented Appliances
If the instrumentation of this boiler replaces an older boiler in a common vent system with other appliances, or if you remove additional appliances from the common vent, all the appliances must be checked for proper venting.
At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation.
1.Seal any unused openings in the common venting system.
Sceller toutes les ouvertures non utilisées du système d’évacuation.
2.Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.
Inspecter de façon visuelle le système d’évacuation pour déterminer la grosseur et l’inclinaison horizontale qui conviennent et s’assurer que le système est exampt d’obstruction, d’étranglement, de fuite, de corrosion et autres défaillances qui pourraient présenter des risques.
3.Insofar as it is practical, close all building doors and windows and all doors between the space in which the appliances remaining connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.
Dans la mesure du possible, fermer toutes les portes et les fenêtres du bâtiment et toutes les portes entre l’espace où les appareils toujours raccordés au système d’évacuation sont installés et les autres espaces du bùtiment. Mettre en marche les sécheuses, tous les appareils non raccordés au systéme d’évacuation commun et tous les ventilateurs d’extraction comme les hottes de cuisinière et les ventilateurs des salles de bain. S’assurer que ces ventilateurs fonctionnent à la vitesse maximale. Ne pas faire fonctionner les ventilateurs d’été. Fermer les registres des cheminées.
4.Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so appliance will operate continuously.
Mettre l’appareil inspecté en marche. Suivre les instructions d’allumage. Régler le thermostat de façon que l’appareil fonctionne de façon continue.
5.Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the
